REPRODUCTION:
I was able to reproduce all 5 failures on an iPad Simulator running iOS 26.2 ToT with the following:

run-webkit-tests --ios-simulator --child-processes=1 --no-retry --exit-after-n-failures=5 --iterations 100 <TESTNAME>

I am going to mark expectations as pass fail while this pends investigation.
